Re: [Yade-users] [Question #706540]: Trouble in generating sphere packing
Question #706540 on Yade changed: https://answers.launchpad.net/yade/+question/706540 Status: Open => Answered Karol Brzezinski proposed the following answer: Hi Huan, For each radius, I prescribed some 'spread', so the radii of particles fall between given sieve sizes (rRelFuzz1 = (0.019-0.0125)/4/rMean1). If you want to have all the particles in a given size to have equal radius, set rRelFuzz = 0 everywhere. In such a case, your colouring method should work. As Jan said, please open a new topic for the new question.
